Summary of the Outcomes of Uncontrolled Cohort Studies Published Before 1990 of Endoscopic Sphincterotomy (ES) and Open Surgical Common Duct Exploration (Surg.).

Years	Intervention	Patients n	Stone Clearance n (%)^*	Additional CBDI needed (ES or Surg.) n (%)^†	Complications n (%)^†	Mortality n (%)	Length of Hospital Stay d (range)
1982–1989	ES	3,818	2,210/2,403 (92.0)	110/3,306 (3.3)	312/3,798 (8.2)	56/3,818 (1.5)	3–6
1972–1990	Surg.	3,606	1,952/2,164 (90.2)	155/2,391 (6.5)	575/3,142 (18.3)	77/3,606 (2.1)	10–16

The short mean hospital stay of patients undergoing ES suggests that mortality rate and hospital stay from the subsequent cholecystectomy were not taken into account.

* The denominators include the total number of patients entered into the trial, after excluding those with suspected but absent CBD stones.

† The denominators include the number of patients with available data.

CBDI, common bile duct interventions; d, day(s).
